It’s time for Princess Syalis to start acting like a proper hostage, so the demon king issues a decree to help change that.
Basically, it's because your hostage
has too much time on her hands.
.السبب هو أنّ رهينتك تملك الكثير من وقت الفراغ
Ist doch eure Schuld, wenn ihr
der Geisel zu viel Freizeit gönnt.
El problema es que su rehén tiene
demasiado tiempo libre.
En gros, tout ça arrive
car elle n’a rien d’autre à faire.
Per farla breve,
 il vostro ostaggio ha fin troppo tempo libero.
Basicamente, é porque sua
refém tem muito tempo livre.
Короче говоря. У вашей заложницы
 много свободного времени.
